Description

Somatostatin 25 is a high-purity synthetic peptide analog of the endogenous hormone somatostatin, identified by CAS No. 75037-26-2. This compound is critical for research and development in endocrinology and oncology due to its potent inhibitory effects on the secretion of growth hormone, insulin, and glucagon. It is an essential biochemical tool for pharmaceutical companies, academic research institutions, and diagnostic manufacturers focused on metabolic disorders, neuroendocrine tumors, and advanced peptide therapeutics.

Application

• Pharmaceutical R&D: Used as a reference standard and active pharmaceutical ingredient (API) in the development of somatostatin analogs for treating acromegaly and neuroendocrine tumors.
• Biochemical Research: Serves as a key reagent in receptor binding studies, signal transduction pathway analysis, and in vitro bioassays to understand hormonal regulation.
• Diagnostic Kit Production: Employed in the calibration and development of immunoassay kits for measuring somatostatin levels in clinical and research settings.
• Academic & Preclinical Studies: Utilized in animal models and cell culture studies to investigate the physiological roles of somatostatin and evaluate potential therapeutic agents.
• Peptide Chemistry: Acts as a building block or intermediate for the synthesis of novel, more stable, or targeted somatostatin receptor ligands.
